ConnectOracle

Overview

The ConnectOracle contract interacts with the Cosmos blockchain to fetch and process price data for various currency pairs from the Connect Oracle.

Imports

Import File	Description
`ICosmos.sol`	Interface for interacting with the Cosmos blockchain.
`JsmnSolLib.sol`	Library for JSON parsing.
`IsoToUnix.sol`	Library for converting ISO date strings to Unix timestamps.

Structs

Price

A struct to hold price information.

uint256 price: The price value.
uint256 timestamp: The timestamp of the price.
uint64 height: The block height at which the price was recorded.
uint64 nonce: A unique identifier for the price record.
uint64 decimal: The decimal precision of the price.
uint64 id: The ID of the price record.

Constructor

constructor() {}

The constructor initializes the contract. It does not take any parameters or perform any actions upon deployment.

Functions

get_price

Fetches the price for a specific currency pair from the Cosmos blockchain.

function get_price(string memory base, string memory quote) external returns (Price memory)

Parameters

Name	Type	Description
`base`	`string memory`	The base currency of the pair.
`quote`	`string memory`	The quote currency of the pair.

Returns

Type	Description
`Price memory`	A struct containing the price information.

get_prices

Fetches prices for multiple currency pairs from the Cosmos blockchain.

function get_prices(string[] memory pair_ids) external returns (Price[] memory)

Parameters

Name	Type	Description
`pair_ids`	`string[] memory`	An array of currency pair IDs.

Returns

Type	Description
`Price[] memory`	An array of `Price` structs containing the price information for each pair.

join

Concatenates an array of strings with a specified separator.

function join(string[] memory strs, string memory separator) internal pure returns (string memory)

Parameters

Name	Type	Description
`strs`	`string[] memory`	An array of strings to be concatenated.
`separator`	`string memory`	A separator to be used between the strings.

Returns

Type	Description
`string memory`	The concatenated string.

get_price_from_tokens

Parses a JSON string to extract price information and populate a Price struct.

function get_price_from_tokens(
    string memory json,
    JsmnSolLib.Token[] memory tokens,
    uint256 priceObjectIndex
) internal pure returns (Price memory)

Parameters

Name	Type	Description
`json`	`string memory`	The JSON string containing the price information.
`tokens`	`JsmnSolLib.Token[] memory`	An array of JSON tokens.
`priceObjectIndex`	`uint256`	The starting index of the price object in the tokens array.

Returns

Type	Description
`Price memory`	A struct containing the parsed price information.
